The large-scale PV systems are seeing a rapid growth as innovations are marching towards improving economics and increasing global renewable energy potential.
FREMONT, CA: World's leading DC optimizer company, Ampt has sees a vast adoption of its string optimizer products. The company has embraced the large-scale adoption of PV solar and storage projects summing up to gigawatt-hour (GWh). Ampt String Optimizers are DC/DC converters, delivering higher performing solar and storage systems uniquely with minimum costing solution. These optimizers enable low-cost DC-coupled solar and storage systems and provide string-level data for improved O&M. For instance, String Optimizer models are for system voltages that range from 600 to 1500 VDC. It has two inputs and one output back to the inverter. The String Optimizers are located between the combiner box on a PV system and the PV source circuits. The optimizer implements MPP tracking on every input, delivering sufficient available power to the output at a voltage set by the inverter. This is done without any required communication between the inverter and optimizers.
Ampt attributes the recent series of projects to the adaptive technology in its String Optimizers. It delivers value to a wide range of system sizes and storage applications. These projects have integrated solar PV with DC-coupled energy storage, including PV systems ranging from 50 to 100 megawatts (MW), 10MW. With two- to five-hour charge durations, the PV-to-battery-to-inverter ratio on these systems ranges up to 2:1:1.
This recent development is another milestone for industry recognition for the value that Ampt optimizers and DC-coupled energy storage bring to solar. PV systems provide energy on demand, including energy storage and support grid stability. The solar array can charge DC-coupled energy storage system batteries directly. This will reduce the cost per megawatt-hour compared to AC-coupled approaches. Ampt String Optimizers systemize PV array and power components operation with a fixed and high DC bus voltage lowering the cost of both the DC/DC battery converters and DC/AC inverters. These optimizers use wireless communications to provide high-accuracy synchronous string-level data. This will enhance the effectiveness of Operations and Maintenance (O&M).
Ampt serves the global market of large-scale PV systems where dependability, scalability, productivity, cost and control are of prime importance. The company delivers innovative power conversion and communication technology, providing system-level optimization of PV power plants. Ampt products feature a patented technology that facilitates PV systems to deliver more value than conventional system designs. It offers simple and affordable ways to upgrade existing PV systems to produce more energy. These are distinguished from other solutions by uniquely delivering a true spend-less-get-more value proposition. Ampt optimizers save on electrical BOS, inverter, and additional costs to lower total PV system cost. Ampt's patented technology innovation allows for more modules per string to eliminate electrical BOS components and labor having higher power density to lower the cost per watt. Ampt serves the global solar market with renowned products, bagging strategic partners across the globe.
